It's got a later model swingarm (I believe one of the 'Deltabox' style) ones, 17" CBR rear wheel conversion, with a rear shock off a 20xx GSX-R600.

I'm planning to have the rear shock resprung and revalved this winter, to get ready for the 2019 race season, but want to make sure the rear shock geometry's proper, before I take my sag measurements and ship it to RaceTech. I've got the preload maxxed out now but there's still way too much sag for my 175#, so I know it at least needs a respring.

Anyone running an FZR frame with Deltabox swingarm and Jixxer shock? If so, what are your dogbone lengths? And swingarm angle?
